Usability testing. Usability testing is too often used innapropriately in my opinion. Compared to other research techniques, it’s fairly cheap and easy to organise. But this leads to it being used to answer research questions it often can’t answer. In this post I’ll discuss how I think the UX community is losing touch with some of the basics.
Usability testing. One of the simplest ways to measure any event is a binary metric coded as a 1 or 0.

Usability testing. You don't need a PhD in statistics to understand and use confidence intervals. Because we almost always sample a fraction of the users from a larger population, there is uncertainty in our estimates. Confidence intervals are an excellent way of understanding the role of sampling error in the averages and percentages that are ubiquitous in user research.
Usability testing. You can't conduct user research without users. But rarely can we talk to all users in the population we're studying, whether they be consumers, lawyers, doctors or iPhone users.

Usability testing. There are many reasons why usability professionals don't use statistics and I've heard most of them. Many of the reasons are based on misconceptions about what you can and can't do with statistics and the advantage they provide in reducing uncertainly and clarifying our recommendations.

Usability testing. The usability data that we collect from remote testing comes in two forms: quantitative and qualitative. We can express quantitative data with numbers, such as how long a user stayed on a page, how many visits a page gets, or by serving up a survey asking users to rate an aspect of a site on a numerical scale. On the other hand, qualitative data is generally expressed in words, such as answers to open ended survey questions.

Usability testing. Everything should be 1 click away. It takes too many clicks !For as long as there have been websites it seems that there's been a call to reduce the number of clicks to improve the user experience. This was especially the case after Amazon released its one-click purchase button in 1999. Executives, product managers and developers at one point have all joined the call to reduce the number of clicks.
